我无法使用 jdbc 连接到 oracle 数据库。

错误：无法连接到 jdbc:oracle:thin:@localhost.localdomain:1521:orcl 的数据库（用户名：system，密码：tiger）

但是，我可以使用 sqlplus 命令连接它。

这是日志：

java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
Version = Sun GlassFish Enterprise Server v2.1
Testing Database Connection ...
  -- Failure! java.sql.SQLException: Io exception: The Network Adapter could not establish the connection

这是 listener.ora：

 LISTENER =
 (DESCRIPTION_LIST =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
   (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /home/oracle/app/oracle

lsnrctl 的输出：

Listening Endpoints Summary...
 (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC1521)))
 (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=::1)(PORT=1521)))
 Services Summary...
 Service "orcl" has 1 instance(s).
 Instance "orcl", status READY, has 1 handler(s) for this service...
 Service "orclXDB" has 1 instance(s).
 Instance "orcl", status READY, has 1 handler(s) for this service...
 The command completed successfully

tnsnames.ora 的内容：

 ORCL =
   (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

我正在使用 Oracle 11g、glassfish 服务器 2.1、Redhat linux 企业版 6。

任何帮助将非常感激。

尝试在连接字符串中替换localhost.localdomain为localhost，即

jdbc:oracle:thin:@localhost:1521:orcl

如果我用作地址，我也会得到一个The Network Adapter could not establish the connection错误，如果我localhost.localdomain只使用它就会消失localhost。

测试 ：

 telnet localhost 1521

如果它不起作用

设置 iptables ：
